William Wynn Westcott (17 December 1848 – 30 July 1925) was a coroner, ceremonial magician, theosophist and Freemason born in Leamington, Warwickshire, England.

[3] Wescott co-founded the Hermetic Order of the Golden Dawn with Samuel Liddell MacGregor Mathers and William Robert Woodman in 1887, using the motto V.H.

Around this time, he was also active in the Theosophical Society, where he founded in 1891 the Adelphi Lodge in London WC.

In 1896, he abandoned public involvement with the Golden Dawn due to pressure regarding his job as a Crown Coroner, with which it was seen as an unseemly association.

He retired as a coroner after 1910, emigrated to the Union of South Africa in 1918, and died in Durban in 1925.
